ABSTRACT:
A portable, self-stabilizing folding seat support for use on ground conditions of various consistencies comprising a rigid main shaft, a plurality of pivoting stabilizer feet and stabilizer feet brackets attached to the base of the main shaft, and an adjustable stabilizer shaft which can be extended beyond the base of the main shaft and pivoting stabilizer feet to various positions. A removable stabilizer shaft cross bolt is used to fix the adjustable stabilizer shaft in various degrees of extension in relation to the main shaft and stabilizer feet, and a retention leash flexibly attaches the stabilizer shaft cross bolt to the main shaft and prevents its loss. The seat support may be used to provide a self-stabilizing seating platform on soft unstable ground conditions by vertically thrusting the extended stabilizer shaft into the soft ground or mud so that the extended stabilizer feet engage the soft surface. The seat support may be used to provide a self-stabilizing seating surface on hard ground or floors by extending the stabilizer feet and placing the seat support directly on the hard surface without extending the stabilizer shaft beyond the base of the main shaft and stabilizer feet.
